藍菌素 的英文怎麼說
中文拼音 [lajūnsù]
藍菌素
英文
cyanein-
To see what was going on, he labelled the doxycycline - resistant strain with a yellow protein and the sensitive strain with a blue protein
為了觀察進行情況，他用黃色蛋白質標記耐脫氧土霉素的大腸埃希菌，用藍色的蛋白標記對脫氧土霉素敏感的細菌。Under that condition the strain can produce the most concentration of the bioactive compounds. the physical and chemical properties of the actibacterial compounds have been studied, the results showed the bioactive substance has heat stable, acidity and weakly alkali stable. it can be dissolved in acid water, chloroform solvent, can not be dissolved in ethyl acetate, petroleum ether, alkali water. the result of thinlayer chromatography showed the bioactive compounds can give off blue and green fluorescence in the uv light. the paper chromatography demonstrate the bioactive substance may be a new construct compounds
研究表明，該活性物質具有較強的熱穩定性， ph 9的條件下能穩定存在，但ph 12的強堿性條件下活性物質的抗菌活性幾近喪失；活性物質易溶於氯仿、酸性水、不溶於乙酸乙酯、石油醚、堿性水；薄層層析顯示活性物質在紫外光下能發藍綠色熒光等特點；由捷克八溶劑系統紙層析鑒定該抗菌活性物質不屬於四大類抗生素，可能為一新的抗菌活性物質。Price, a. c. et al. " inhibition of b - ketoacyl - acyl carrier protein synthases by thiolactomycin and cerulenin. " j. biol. chem. 276 ( 2001 ) : 6551 - 9
硫乳黴素與淺藍菌素對酮酰基酰基載體蛋白合成酶的抑制作用， 《生物化學期刊》 276 （ 2001 ） : 6551 - 9Our experiment indicates : ( 1 ) the optimal concentration of kanamycin for screening torenia fournier regenerated buds was 400 mg / l. the ideal transformation was obtained in the following conditions : the leaf discs were dipped in agrobacterium suspension that od600 was 0. 1 for 10 ~ 20 min ; subsequently cocultivated on the ms solid coculture medium containing 20umol / l acetosyringon for 7 to 8 d at 23, and the induction ratio of regenerated buds was 27. 2 %
研究結果表明： （ 1 ）篩選藍豬耳轉化芽的最適卡那黴素濃度為400mg l 。 od _ （ 600 ）為0 . 1的菌液濃度菌液浸染葉盤10 20min ，固體共培養基（含20 mol l乙酰丁香酮）上23共培養7 8d可獲得理想的轉化效率，轉化芽誘導率為27 . 2 ； 16h光照， 8h黑暗是較理想的共培養光周期；莖段是較好的轉化受體。分享友人
